How we work
Accounting should be simple. One fee, everything handled, with a team that knows your business and responds when you need them.
Meet the team
ClearSum is a small, dedicated team. That's deliberate. Every client works directly with us.

Harry Whittington
Founder
CIMA qualified with over a decade of experience spanning hands-on accounting and Finance Director roles. Harry handles all client relationships, advisory and financial strategy. He started ClearSum because he believed business owners deserved better from their accountant.

Abi Whittington
Operations Manager
Abi joined ClearSum in January 2026 to support the growing practice. She handles bookkeeping, payroll, marketing and the operational side of the business, making sure everything runs smoothly behind the scenes so clients always get a responsive, organised service.
